Mullions

Series 300 Security Mullions

The ultimate security partner for both 3700 Rim and 3600 Vertical Rod devices, these removable mullions are made from steel-reinforced aluminum.  A simple removal system for easy in, easy out convenience and matching anodized finishes make them the right choice for pair-of-doors applications.  Easily cut for a perfect field fit, these mullions come with heavy duty strikes and are available in sizes up to 9 feet.  Color matched security clips provide an added level of security overcoming the natural twisting of the door stile under pressure.
